Gjerstad, who concentrates on alto sax but also plays clarinet and flute, has contributed to more than 50 recordings since beginning his career in the 1970s. He too has played with Peter Brötzmann, and also has performed with many other well-known improvising musicians, such as William Parker, Borah Bergman, Derek Bailey, and Evan Parker.

Admission to the Fred Lonberg-Holm/Frode Gjerstad performance will be "$10-$15 suggested" at the door, a price that includes "free beer/wine/food."

Braxton, former front man for the experimental rock band Battles and the son of famed saxophonist/composer Anthony Braxton, has created a wide variety of music during his career, ranging from a recent duo collaboration with Phillip Glass to symphonic works such as his album Central Market, which has been performed live by orchestras including the London Sinfonietta and the Los Angeles Philharmonic.

His multimedia installation "HIVE" recently premiered at the Guggenheim Museum in NYC, with an accompanying soundtrack set for release next month on Nonesuch Records.

Braxton (pictured, center left) will perform solo at The Luminary, with St. Louis' Hylidae as opening act. Tickets are $15 in advance, $17 day of show.

Now, Wash U has announced another performance by Barker (pictured, bottom left), a free event at 7:00 p.m. Friday, April 8 in the auditorium (aka Room 100) of Brown Hall, which for many years has been a site for film screenings on campus.
